The present invention relates to a novel arrangement of sheet piling toprovide a composite wall of caisson sheet piling, with the optionalinterposition of ordinary sheet pil-' ing, using only single U, H or Yshaped members which may be easily made by rolling.

One of the objects of the present invention consists in a new connectingmember for use in joining the individual members.

Another object of this invention consists in caisson sheet piling havinggreat resist ance to bending and permitting progression of the row ofsheet piling in the two directions of movement, from a given startingpoint.

The said improvement consists in the use of a new assembly member orclaw for assembling together rigidly the channel shaped sections.

This assembly member, which can be rolled,

comprises two branches with dove-tailed re-- cesses and a third branchforming a clovetail tenon.

The invention also relates to the construction of a box shaped sheetpiling element by connecting two channel sections rigidly to- .getherbefore they are driven in, by means of two claws such as those specifiedabove, the tenon of one of these claws being if desired provided with athird claw comprising two dove-tailed recesses.

Various embodiments of the invention are illustrated by Way of exampleand in a nonlimiting manner in the accompanying drawings.

In the drawings:

Figure 1 shows the form of the assembly member or claw according to theinvention.

Figures 2 and 3 show two box-shaped sheet piling elements constructedwith the claw forming the subject of the invention.

Figure 2 shows the first sheet piling element to be driven in and Figure3 the sub sequent sections.

Figure 4 shows a line of wall comprising both box shaped elements andordinary elements.

Figure 5 shows a modified form of sheet piling formed of box shapedelements, comprising a lengthemng section forincrea sing ANONYME' beformed provided with connecting means positioned in such a way as toenable them to be secured to the adjacent sheet piling elements.

The invention provides in particular. for

the construction as anew industrial product of box shaped sheet pilingelements as shown in Figure 3, and formed by rigidly connecting togethertwo channel sections such as 1 before they are driven in, these sectionsbeing as s'embled by means of two claws such as 5, the tenon 5d of oneof them being fitted with a claw 2 analogous to the claw described in mysaid prior specification. 1

By virtue of this arrangement it is pos sible 'to construct easily aline of box shaped sheet piling elements by guiding the open lodgment inthe ordinary claw 2 each time over the tenon shaped branch of the claw5of the element previously driven in. Thefirst sheet piling elementdriven in does notv comprise an ordinary claw'2 as will be seeninFigure2. r :5

In Figure 4, which shows a line of sheet piling comprising both boxshaped elements and Z-shaped elements, it will be noted that in order toconnect together a box shaped element and a Z-shaped element, use ismade of a claw2Qcomprisingtwo lodgments the center lines of which formasuitableangle With each other.

In Figure 5" theinoment of inertia of the box shaped elements isincreased bythe use of extension sections 3 placed in' alignment withthe flanges of the channel sections 1. I

What I claim is 1 1. For "use-in th'e'construction of caisson sheetpiling" by joining before ramming U- shaped members having wingsterminating in similar ends in alignment with these wings,

a Y-shaped massive connecting member having two recesses opening indiverging direcs tions and comprising between them a part of the saidmassive member and each adapted to encase one of the wing ends of the U-shaped members thus spaced apart, and a tenon similar to the wing ends,the median plane of this tenon passing through the intersection of themedian planes of the two hollows. V

2. For use in the construction of caisson sheet piling by joining,before ramming, U-v shaped members terminating in trapezoidal ends withtheir large axis directed along the extension of the wings of thesemembers, a Y-shaped connecting member comprising trapezoidal hollowsopening in diverging directions and each adapted to house one of thetrapezoidal ends of the wings thus spaced apart, and a trapezoidal tenonintegral with the Y'-'shaped member, the median plane of which passesthrough the intersection of the median planes of the other two arms.

3. A caisson pile for forming a row of sheet piling made by rigidlyjoining, before ramming, two U-shaped members with wings terminating insimilar ends in alignment with said wings and with their opening andtheir wing ends arranged face to. face, with two Y-shaped connecting,members which join the wing ends of the. U-shaped members, eachconnecting member comprising two hollows opening in divergingdirections,and each adapted to encaseone of the wing ends of the U-shaped membersthus spaced apart, and a tenon,'similar to the wing endswhich extendstowards the exterior of the pile, the

' median plane of this tenon passing through the intersection of themedian planes of the two hollows. r

r 4- A caisson pile for forming'a row of sheet piling made by rigidlyjoining, before ramming, two. U-shaped members with wings t'erminatinginsimilar ends and in alignment.

with said wings and with their opening and ther wing ends arranged faceto face, with two Y shap'ed connecting members which join the wing endsof the U-shaped members, each connecting member comprising two hollowsopening in diverging directions, in each of which one of these ends thusspaced. apart is housed, and a tenon similar to the wing ends, whichextends towards the exterior of the pile, the median plane of this tenonpassing through the intersection of the median planes of the twohollows, and a substantially H-shaped member comprising two similarhollows, one of which cases the tenon of one of the Y-shaped members.

In testimony whereof I have aflixed my signature. p I
